Its all consumer hardware but it's a dedicated box running unraid.
Ita easy to do in unraid, you set it up per share, so say you have a "media" share you can change the settings to include a cache drive and then set it to write to the cache drive first and then more to array. If you don't have a cache drive or want to add a other you can do that by installing the ssd, booting up, stopping the array and adding in a new cache drive (you can add it to your existing cache pool to increase its size or create a new one and keep them separate for separate uses)
I use unraid with 5x8TB drives, 1tb ssd as a cache drive for new transfers (writing to an ssd is faster, it then moves to the array after) 500GB NVME drive for appdata and applications and a 250GB ssd for VMs and ISOs
I never made such a comment. Gaming, for me is a big reason why I only have windows installed on my PC (and adobe) there are games which work on Linux (either natively or with Proton) but some games I play, don't. Theres no point in me dual booting as, let's be honest, dual booting just adds more steps and overcomplicates things. I use Linux on my laptop as the alternatives I use (Darktable and Kdenlive) are more than good enough for when I'm on my laptop (its not exactly a powerhouse) but when I'm on my desktop I want to use Lightroom, Photoshop and DaVinci Resolve as they are more refined and fit my workflow better.
Unraid on my server is just because its exactly what I need.
Not sure about your life, but I don't count things I enjoy as "work" especially when its not work. I enjoy using Linux, I enjoy my home lab why should I need to justify it when it brings me joy? Linux works for me and my workflow, just because it doesn't work for yours, don't try to shit on other people.
There are alternatives to these so it depends on the user. If your workflow requires these, then that's in you.
Like what, what format would this be? Regardless every company I have ever worked for issue me a laptop with windows anyway, so why would the OS I choose to use on hardware I own be a factor for work? Even then, if they didn't I don't know of any format that I would need that would be an issue.
Well in that case; My windows PC falls back to a server running Linux as that's where all my files are, where my docker containers and VMs all run off.. I can spin up a new PC in minutes (windows or Linux) as everything is done off the server, including staging my devices.
When you absolutely need to use Windows Defender... On Linux. Or when you need to use Cortana /s
Windows only app... Name one that is actually useful and I bet there is an alternative.
I don't need it for windows applications, its basically something I can use for light photo and video editing and uploading to my server, all the heavy lifting is done on my PC which has windows because of adobe and better support for X264 and X265 when video editing.
Check out Spaceinvader One on YT, he alone is all you need when it comes to everything and anything unraid.
